Self-powered 4g antenna. External LTE antenna

Currently, 3G technology allows instantaneous voice communication and data transmission. There are three main types of antennas Huawei, ZTE and others, which are necessary to improve the premium signal signal at frequencies of 2100 MHz (3G), 2600 MHz (4G LTE), 900 MHz (2G / GSM / 3G) and is available to a private client: straight, all-directional and panel antennas.
Directed 3G, 4G LTE and GSM antennas of the “hedge channel” or Yagi type, as they are called behind the cordon, require precise settings and adjustment (pointing) of the antenna to the operator’s base station (BS) in order to obtain the maximum speed from the source. Huawei/ZTE direct antennas have the same maximum power as other types of antennas. The actions of the building will ensure the signal there, where before, with a range of up to 10 km (depending on the frequency). Directional Yagi antennas are often used in the area: in rural and private cabins, at dachas, cottages, garden cabins, etc.
All-direct (or circular) 3G/4G LTE/GSM antennas of Huawei/ZTE can receive signals from any direct lines and are not directly directed to the local BS. Most circular antennas are mobile, then. easy to transport, but also stationary all-direct antennas Huawei. As a rule, stinks appear on magnetic bases for use on cars. This type of antenna is suitable for homeowners who want to strengthen a strong but weak signal. The gain coefficient for all-direct antennas is much lower than for straight antennas.
Panel antennas 3G and 4G LTE are in the middle between stationary direct and stationary circular. The smell is much simpler when the operator is pointed at the BS, but also requires careful installation and adjustment. The strength of Huawei panel antennas is usually higher, lower for circular antennas, and lower for straight antennas. Type of panel antennas – 3G/4G LTE MIMO panel antennas (antennas with dual polarization) are usually found in the 4G LTE standard, and sometimes in 3G. Most often, MIMO antennas are panel-type, but there are also circular (all-direct) MIMO antennas, and direct-directional MIMO antennas, “whip channel” or log-periodic.
There is also a fourth type of 3G/4G LTE/GSM antennas – or rather, a variety of all-direct ones – so-called clip antennas, which are designed for mounting directly on the screen of a consumer’s laptop. This type is best suited for traders who want to increase the price and buy their computers in areas with a good signal. The antenna-pinch (and this is how “clip” is translated from the English language) is used not so much to strengthen the signal as to support it. The strength coefficient of Huawei / ZTE clip antennas is the lowest of all.

Operating frequencies between 3G and 4G LTE, due to their technical features, can have good penetration, but even worse coverage - up to a maximum of 2 kilometers from the base station in the line of sight zone - which, of course, changes several times ів through those that hvilya yaka screens Practically, no matter if there is any disruption (even if not too much), as a result, the strength of the signal even drops when reaching the subscriber. For this purpose, the necessary antennas, which in most cases are sufficiently placed on the windowsill from the outside, or from the inside side of the window, and in order to reach the signal of the threshold - in case of a different device їin the third and fourth generation between the places, and beyond the places, in the region, “in the fields” it is recommended to use straight panel antennas and “whip channel”, which can increase the intensity up to 2 times more per circle. Another problem, or rather a different type of first, is associated with the work of the border in the area - this type of filth is associated with the peculiarities of locality: lowlands, foxes, and so on, the antennas are mounted on the ground according to the principle of greater, greater no matter what You must also remember that external direct antennas must be directly directed to the nearest operator base station.

The vicor of the all-direct antennas in the sphere is interconnected, because They are subject to stronger directives, and the number of base stations in the area is significantly lower than in the area. Another problem is that there are dozens of modems of different transmitters that have different antennas, usually of two types: TS9 and CRC9, so when choosing an antenna you need to know exactly the model of your modem or the model you are choosing to buy uvati.

Before you buy a 3G (UMTS) or LTE 4G antenna for a USB modem Megafon, MTS, Beeline, YOTA, Rostelecom (and this device itself is the most widespread among all communication operators) or a router (router), you need to understand what to do - some antennas are subject to exchange: thus, having purchased an external direct 3G/LTE 4G antenna, the subscriber has the right to purchase a supplementary signal for a 3G/4G LTE modem at a distance of no more than 5 km from the operator’s base station: the 3G coverage radius becomes less than 2 -2.5 km, and LTE 4G - even less - 1.5-2 km. For people who live more than 5 km from the operator’s base station, it is necessary to use signal boosters - repeaters that can “bring the subscriber closer to the base station, or even if they are located 10 km or more away above the operator's tower. It is also necessary to know that 3G/4G LTE boosters (repeaters) or “active antennas” as they are called, as a rule, are not universal for both frequencies per antenna, which can operate on 2 frequencies 100-2600 MHz, and there is a clear division of frequencies: either 3G or LTE 4G. There are repeaters that operate on both frequencies, but usually there are two repeaters in one case - the price of these devices is such that it is easier to buy two boosters of different frequencies, one of which is “universal”.

Warto is closely connected to antennas and booster YOTA - LTE 4G antennas, which will pick up the signal of the most popular fourth-generation operator. By the way, they do not interfere in any way with 4G LTE antennas for MTS and Megafon operators: the same operating frequencies are 2500-2700 MHz, the same types are direct and all-direct, but with one additional caveat: YOTA modems are administrated as a modem Other operators do not accept standard connectors for the 3G / 4G LTE antenna (CRC9 or TS9), so connecting the antenna to them becomes problematic - either drill out the openings yourself and “reach” the service connectors MS156, or “solder in” standard connectors (for example, SMA ) yourself. Most homeowners won’t be able to do this, and for them the generators themselves have chosen antennas with a built-in modem - the modem is soldered into a panel 3G antenna, and the robot works with it using an additional USB cable. These MIMO antennas YOTA are more external, but there are also copies for installation in the middle of the future. These antennas have proven themselves poorly, so later the manufacturers began to produce universal antennas with built-in 3G/LTE 4G modems - the user can access the modem and can easily change operator SIM cards.

It is important to note that the price of 3G/4G antennas will not always depend on the increase: dimensions, ease of installation, aesthetics, etc. play a significant role.

A lot of koristuvachs joke around in search systems on the Internet t.z. modem boosters or signal boosters for modems, without understanding how the devices operate or look the same. Antennas, in essence, are the very power of modems.

Searchers have had a lot of questions on the topic of 3G 4G LTE antenna with their own hands: the widest options for self-made antennas are “biquadrat” or Kharchenko antenna, “Hwyli channel” or Yagi antenna, panel antenna - phased array or contour antennas. And since it is quite simple to make a bi-square yourself - the required copper wire and a small sheet of metal, and the complicated layouts can be found on the Internet, then the Yagi antenna can be built much more easily, although the layout is not much more complicated, and say nothing about the panel antenna - people, The one who sticks with him is unlikely to stick with him the first time. So, for a Yagi antenna you need aluminum tubes or steel rods and a tool for fastening them (for metal rods - a welding machine), for a panel antenna - a metal sheet, metal scissors and a tool. You also need to understand that it’s easier to build a 3G 4G LTE antenna with your own hands, because it has less strength: for the Kharchenka antenna - up to 8-9 dBi, for the hvil channel - up to 16-18 dBi, for the panel antenna - up to 20 dBi.

Antenna adapters (pigtails) for connecting modern high-power antennas to modems and mobile routers of the third (3G UMTS/HSPA) and fourth (4G LTE) generations, suitable for all USB modems and portable routers, etc. there are antenna roses, maybe mothers of roses From the other side: FME-male, N-male, SMA-female.

Universal 4G LTE+3G modem. The antennas have roses and are small in size. It works with any SIM cards of all Russian and European operators (YOTA, Megafon, MTS, Beeline, Rostelecom, Tele2, Altel, Motiv, Tattelecom/Litai etc.). Supports speed up to 100 Mbit/s. Ideal for using laptops outside the border.

Prologue.

If you find it difficult to choose an antenna, then you will save your time by simply calling us, because you want to contact everyone yourself, then read on.

Nowadays, people often start to flock to us, wanting to get an antenna for their 3g or 4g(lte) modem, but not knowing how to get the antenna they need and that they need to connect the antenna to the modem. This article will clearly explain how to select an antenna and how to connect it. Through a great deal of information, the article is divided into several parts in the form of other articles.

Part of the persha. Antenna vibration.

Our store has all the antennas available for use in 3g and 4g ranges, including straight ones. They can be classified as follows:

Behind my robot frequency range(I'm grateful)

behind strong

behind type and to the outsider's eye

Frequency range. To start, you need to understand the signal of what you are trying to understand. If you decide to receive an Internet signal from a landline operator, you will need to know the 3g, 4g, or other limits. Then you need to understand which frequency range requires an antenna. Within the operating frequency range, antennas for modems can be divided into three types:

Stronger antenna. Once you have selected the antenna range, you will need to select the antenna strength. The strength of the antenna on our website is indicated by dBi. It's roughly like this:

• lows up to 9 dBi - not available at the store ( This is so popular in the “Kharchenko antenna” category, and so is the “biquadrat” for the ideal setup)

  average 13-14 dBi

  press 16-17 dBi

  very tight 20 dBi

The skin has three decibels of strength – that’s twice the amount of tension. An antenna with a gain of 20 dBi will be twice as strong as 17 dBi, at least as low as 14 dBi, and as strong as 9 dBi. For more details about the difficulty of choosing an antenna, read this article: There will be peace here

Panel ( 13-14, 16-17, 20 dBi)

Khvilovy Yagi Canal ( Udo-Yagi, Yagi) (in stock 14, 17 dBi)

trimmers for parabolic mirror antennas ( the collection looks like an antenna for satellite TV) (Make sure to keep in mind the size of the mirror, we have 22 dbi)

For days there was an opportunity to protest the 3G and 4G antennas not far from St. Petersburg, which we were about to speed up.

Our orderly bad signal to the mobile Internet, but only on the other side of the private booth, since the office is located downstairs on the other side of the booth, it was no longer easy to use mobile goods. Therefore, it was decided to investigate the feasibility of immediate access, and to verify the feasibility of outdoor 3G/4G range antennas on the right of the clear channel connection between the nearest base station and USB modem, then transfer it to the Wi-Fi router for distribution, and connect the cable to the office to the main computer.

The following fates were taken in the experiment:
- Outdoor/room panel antenna URSA 4G (2300-2700 MHz, 18 dB, 31*31*2.2 cm, N-female);
- Outdoor parabolic antenna LIBRA 3G (1920-2170 MHz, 21 dB, 90*60 cm, N-female);
- USB modem Megafon M-150-1;
- 5-meter cable folding 5D-FB with N-connectors, Aileron 5m-5D-FB;
- Pigtail adapter for the Aileron-CRC-9-N-female modem.

Much has been written about the modem, it’s a good model, we appreciate the ability to connect MIMO antennas, and in our test the antennas do not support MIMO capabilities.

For the 4G range we will use the URSA 4G antenna, compact, neat, mounted on a bracket on our stand, and a bracket under the arm. Photo:

For the 3G range, a very large LIBRA 3G parabolic antenna is used, which is based on the width of the military locator
Grati 90 cm! Photo:

The technical exit to the facade/visor of the booth was only possible on one side, which limited our options when choosing the operator’s base station, and judging by the confidential information from the OpenCellID.org resource, 4 km from the installation point a length of street antenna and a number of base stations of the Megafon operator - NW. We have been fully aware of this option, even though the theoretical range of 3G/4G signal coverage is 8-10 km, so we are 100% in the normal coverage area, below the map.

You can also quickly use the FindTower program for iPhone or the Internet resource netmonitor.ru.

The main purpose of all these resources is to show the growth of mobile phone operators on the map of locality.

Before we begin our dances with tambourines, I would like to say a few words about the mobile Internet. Few people are aware that mobile Internet traffic is not a priority for the operators of industrial networks; moreover, in some cases, the transfer of digital data, the Internet and video is right for them zero income, and sometimes a complete profit. The main source of income for them is voice connections, everything else comes from additional options, marketing moves and positions of prestige. Therefore, operators should adjust all their possessions in such a way that they first secure the consumption of voice connections, and then send the excess to Internet traffic and, moreover, operators record the traffic of their base stations and their companions iv, if you deny access to mobile Internet, use it wisely, and even the operator can selectively limit you to the speed and number of digital channels in your sector of the base station and will be completely right, the rest of its technical capabilities, cost and that income will be more important for you and me.

Now, before connecting the LIBRA 3G carrier parabolic antenna, you will get a picture of the connection and speed of data transmission:

Before connecting the URSA 4G antenna we had:

The antenna on the right is very important, and ideally you need to work with a hand-held spectrum analyzer to get the signal from the live broadcast, so you can move, identify your base station and adjust to the maximum y rhubarb. Since there is no radio signal spectrum analyzer, you can’t do without a tambourine, a modem or a mobile phone. Our distance from the base station was not large, so we went straight to the choice of the other utility provided by the megaphone software, which was sufficient. If the signal is weak, use a spectrum analyzer.

Well, by the way, we have captured it on the 3G band:

І on 4G bands:

We were pleased with the results, especially considering the compactness of the 4G antenna and the reduced speed.

In the online store GSM-Repeteri.RU you can buy antennas for receiving and enhancing the 4G standard signal (mobile communications and the fourth generation Internet).

In order for the 4G antenna to process (receive, transmit and amplify the signal) it must be connected to a 4G network. In a classic system, the 4G signal is strengthened and your role has a 4G repeater (repeater). If you need to strengthen the signal directly on a 4G router or 4G modem, you will only need to connect a 4G antenna to the power socket of the router or modem (which is the same socket).

Should I buy a Yaku 4G antenna?

In our assortment you will find 4G antennas of all possible types (circular 4G antennas, parabolic 4G antennas. Directional 4G antennas) and characteristics (with different indicators of signal strength). From us you can buy unique 4G antennas using a Wi-Fi and Ethernet router. All 4G antennas intended for installation outdoors have a high level of resistance to environmental conditions and temperature changes. Also in this section of our catalog you will find 4G MIMO antennas, which are different from the usual 4G antennas with adjacent channels for receiving and transmitting a 4G signal. MIMO technology allows 4G antennas to achieve approximately twice the speed of reception and transmission of data compared to conventional 4G antennas.

To make the process of choosing a 4G antenna easier, we recommend contacting our representatives. For treatment, you can choose the 4G antenna that will make the most of your 4G equipment.

Virobniks produce two types of external direct 3G antennas. Before the first type there are classic straight antennas “Hwylovy channel” or “Yagi”. The stink intensification coefficient of many elements in the main fluid can reach 21 dB. However, such a design is not important for highly straightened lines. This type of antenna is directly directed to the base station with high accuracy.

Another type of direct external 3G antennas can be connected to panels.antennas for modems . The panel antenna has a body that looks like a flat square or a rectangle. In the middle of the new fabrication, the construction is made of foil textolite or two metal plates. One of the plates performs the function of a lifter, and the other serves as a damper. The gain factor of such an antenna can reach 25 dB. It is stable until the code is changed, does not require high accuracy of adjustment to the base station and sees a stable, strong signal.

Direct external 3G antennas are most often installed near suburbs, country houses, and dachas.

All straightExternal antenna for 3G modem є vertical hoop. Such an antenna is very easy to install and can receive a signal from anywhere directly. The gain coefficient of the omnidirectional 3G antenna should remain below the power supply and become 6 – 12 dB. The widest possible width is 30 - 80 cm. All-direct external 3G antennas are installed to strengthen the signal on water boats in cars, as well as at objects where communication is necessary.

Through a high frequency 3G signal practically cannot be transmitted. If you are far away from the base station, most often in a moving area, you may experience a significant reduction in reception. The peculiarities of the locality's relief also add acidity to the signal. As the alarm booth is located at the bottom, and between it and the base station there are problems,boost 3G signal you will have to install it at the highest possible height - on your budinka or on your goldfinch. When installing a direct antenna, remember the need for precise pointing to the base station.

When purchasing a 3G antenna, please note that it is connected to the operator's base station. If the signal reception is stronger and stronger, it can be achieved up to 10 kilometers from the base station. Moreover, it remains in the line of sight zone.

To strengthen the LTE signal, use a 4G antenna. The design of any 4G modem ensures the visibility of the internal antenna, and the coefficient of its strength is selected at 1 dB. The external antenna is connected to a special socket for the modem. With a strong external antenna with a gain factor of 14 dB, the data transmission speed increases several times with stable signal reception. Make sure that the cable that is inserted to connect the antenna to the modem will weaken the signal by 0.3 - 0.6 dB per meter. To avoid wastage, it is necessary that the cable supply be between five and a maximum of ten meters.

Better stabilizes the signal and provides increased data transmission speedantenna for 4G modem MIMO (Multiple Input Multiple Output). They can also be adjusted to improve connection stability in primary 3G networks.

There is a myth about those who prefer to use their own equipment to improve the reception capacity of 3G/4G signals. In fact, commercial expressions work more efficiently, because they are specially certified and ideally suited for working with 3G/4G modems.

When the modem is paired with an external antenna, manufactured in the factory, the overvoltage is turned off, which can cause damage to the modem and the USB port of the computer. The panel external 4G antenna is subject to theft of the housing, which significantly increases the service life regardless of the leakage of excess fluid.

A weak and unstable signal far from the operator’s base station does not mean that such a place will be able to access the Internet. The installation of external antennas for 3G/4G modems will help install connections in areas shielded by reinforced concrete walls or in remote areas.
